Watch: Supermodel Coco Rocha bust a move for Longchamp’s SS13 campaign video. And we thought her runway strut was impressive.

Check Out: The First Lady’s style evolution. While a lot has changed (from her bangs to her brows), we think she looks perfectly presidential in both.

Hear: The top ten tracks at London Fashion Week. With these jams on our iPods, the sidewalk is our catwalk (or so we like to think).

Own: A piece of fashion history. Ten of Princess Diana’s most iconic dresses will be up for grabs at the Kerry Taylor auction house on March 19. Just be prepared to shell out some serious dough.
